Abstract. In this work we use the multiconfiguration Dirac-Fock method to calculate the transition probabilities for all possible decay channels, radiative and radiationless, of a K shell vacancy in Zn, Cd and Hg atoms. The obtained transition probabilities are then used to calculate the corresponding fluorescence yields which are compared to existing theoretical, semi-empirical and experimental results.

“…In general, the latter are indeed overestimated by theory. For instance, theoretical L 1 Coster-Kronig widths of 14.5 eV, 11.2 eV and 10.7 eV are given in [65] (interpolation between the values quoted for Au and Bi), [66] and [32], respectively. The theoretical Auger widths from the same sources are 2.5 eV, 2.0 eV and 2.1 eV, i.e., 2.2 eV in average.…”

Abstract. High-resolution measurements of the photoinduced X-ray emission of liquid mercury were performed, using a transmission DuMond-type crystal spectrometer for transitions above 11 keV and a reflection von Hamos-type crystal spectrometer for transitions below 11 keV. The target X-ray fluorescence was produced by irradiating the sample with the Bremsstrahlung from X-ray tubes. The energies and natural linewidths of 6 K-shell, 26 L-shell and 2 M -shell X-ray transitions were determined. Using a least-squaresfit method to solve the two sets of equations derived from the observed transition energies and transition widths the binding energies of the subshells K to M5 and O1 and the level widths of the subshells K to N5 and O1 could also be determined.

Vacancy Transfer Probabilities from K to L Shell for Low Atomic Number Elements at 5.96 keV

et al. 2010

Vacancy transfer probabilities from K to L shell were measured using I Kβ /IKα intensity ratios for six elements in the atomic region 16 ≤ Z ≤ 22. The K X-rays from the targets excited by 5.96 keV (1.85 GBq 55 Fe filtered annular source) incident photon were obtained using a high resolution PGT model Si(Li) detector. Theoretical values were calculated using radiative and radiationless transition rates of these elements. The measured values of ηKL were compared with the theoretical ones. Reasonable agreement was typically obtained between present and theoretical values.
